Company History and Business Evolution

The origins of Charles River Laboratories can be traced back to 1947 when Dr. Henry Foster founded the company in Wilmington, Massachusetts, initially focusing on breeding laboratory rats and mice. The UK division was established in the 1970s to support the burgeoning European pharmaceutical market, with the first facility opening in Margate, Kent. Over the decades, Charles River Laboratories UK underwent significant expansion through strategic acquisitions and organic growth. A pivotal milestone was the acquisition of the Inveresk Research Group in 2005, which bolstered the UK’s capability in safety assessment and toxicology. Subsequently, the acquisition of Vital River Laboratories in 2010 expanded its reach in Asia, but the UK remained a core hub for innovation. In 2015, the company invested £40 million in a new, state-of-the-art facility in Edinburgh, consolidating its presence in Scotland and creating over 500 high-skilled jobs. This facility houses advanced laboratories for in vivo pharmacology, bioanalysis, and imaging. The evolution continued with the integration of cell-based assay technologies and the adoption of CRISPR-based modelling, positioning Charles River Laboratories UK at the forefront of precision medicine. The company’s adaptive strategy during the COVID-19 pandemic—rapidly scaling up its vaccine and antiviral testing capabilities—demonstrated its agility and critical role in global health crises. Today, Charles River Laboratories UK operates as a fully integrated CRO, offering services from target identification through to Phase I clinical trials. Its history is marked by a relentless pursuit of scientific advancement, reflected in numerous patents and publications emerging from its UK labs. The company’s evolution mirrors the broader shift in pharmaceutical R&D toward outsourcing, and it has consistently anticipated industry trends, such as the growing demand for biomarker-driven studies and the use of artificial intelligence in data analysis.
